109 E-7 Max Speed Emergency vs Boosted Mode

[BlackBadger]

Hi, just wondering what speed can you guys achieve with the 109 e-7 in boosted mode? Can anybody achieve around 498kmh?  

 

This guide  Aircraft flight and technical specifications and operational details  states 477kmh in emergency mode. (and apparently it's the DB601a, not the a/n?)

 

 Can someone enlighten me on how these values will be affected by seasons? e.g. what environment temperature is the standard and what % deviation is one to expect from summer and winter respectively?

 

 

And am I getting it right -  continuous > combat > emergency > boosted ?

Posts have been made about this plane's performance before. It can not get the claimed 477kmh in emergency mode (1.3ata) even with full negative stabilizer and minimum radiators. I don't know why the devs claim these stats, as the plane can not achieve that performance. 

 

All these values are for standard atmospheric pressure which can be simulated using an autumn map (760 mmHg at 15 degrees Celsius).

On deck, kuban autumn map, with the E7 in combat/emergency/boosted i get : 

461/477/484 kph

 

note : for distinction between combat/emergency/boosted, i used the technochat and not the ata indicator (aka : my emergency test might very well have been at 1.30 ata oa1.31 ata or 1.32 ata)

The manifold pressures are given in the technical details page and using these is the only way to ensure accuracy. I think this is important because using those game labels the boost pressures will be way off. 

 

You can't get 477kmh at 1.3ata as per the maximum speed performance specs. It is clearly slower in game and I don't know why the plane is listed as that, as the other blue and red planes all seem match with their technical performance specs in game.

There  will always be a small error. Devs have stated it multiple times. If you get 470 kph for example, it is within stated error margin.

 

Also, I don't know at which rad settings the speed is ought to be achieved. Optimal temps? Fully closed rads? Maximum allowed temps? 

The difference I get, for the E-7, between fully closed rads and fully open rads is

a) 431kph-465kph for combat power (and 461kph for rads which make the engine not overheat but run very hot ~ roughly about 10% for oil and water)

b) 454kph-488kph for boosted power (and 484kph for rads which make the engine not overheat but run very hot ~ roughly about 10% for oil and water)

 

didn't try fully closed and fully open rads for emergency power, only the ~10% rads for which i got 477 at deck. 

 

 

(tests done on kuban autumn map, boosted is 100% throttle, combat is 76% throttle (Which, I mentioned before, the technochat considers as combat power ))
